Worked on improving the Doris website documentation by addressing a critical issue in the CREATE INDEX SQL example, ensuring the mandatory indexed column list appears after the table name for both Doris 3.x and 4.x versions. This update, made in the apache/doris-website repository, aligned English and Chinese documentation, reducing user confusion and potential misuse of the CREATE INDEX statement. The work involved technical writing and SQL expertise, with changes authored in Markdown to maintain consistency across languages. By refining documentation accuracy and clarity, the update aimed to enhance developer experience and decrease support requests related to index syntax misunderstandings.
